clare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to certain 'new and useful improvements in armor for vehicle tires, and the object of my invention is to 'provide a pneumatic tire of the ordinary typewith an additional armor or protection, whereby the liability of puncture may be decreased/,F the wear and tear taken off the tire proper and the life of the tire increased without affecting the resiliency of the tire.

With these objects in View my invention consists in certain combinations and arrangement of parts, the preferred form of which will be first described in 'connection with the accompanying drawings, and then the invention particularly pointed out in the claims.

Referring to the drawings wherein the same part is designated by the saine reference numeral wherever it occurs, Figure l is a side elevation of a vehicle Wheel having a pneumatic tire and provided with my invention, a part oi the armor oi the tire being broken away in order to more clearly show the construction. Fig. 2 is a section taken along line 2, 2, Fig. 1. Fig. 3 is a perspective view oi one of the sections ofY the armor.

' Fig. 4 is a view similar to Fig. 3, showinghowever only between .the sections and the retaining bands.

` of the tiro,

one ond of a section, the form oi the end of the section being slightly modified. Fig, 5 is apcrspective view of one of the retaining bands for the sections, showing an end of one oi the sections removed therefrom. Fig. l 6 is a detailed yiew of a modified form of connection' Fis: 7 is a detailed ection on line 7 of Fig. 1.

ldesignatcs a wheel having a rim 2 to which is secured the ordinary pneumatic tire 3. In the form of my inveniiion shown, this pneumatic tire is'of the ordinary type, comprising an inner tube, and a shoe which is secured to the rim by the ordinary clench construction,

4 are a series of protecting sections which are arranged around theiperiphery of the tire, as shown in Fig. l. Those sections are qurved to ccniorm 4to the periphery and their ends are so cut that wlienthey are placed on the tire, the ends coincide with the' radii of the wheel, whereby theonds of the adjacent sections will abut against each other. The sections are of such a width that they do not completely surround the tire and preferably, and as shown,.tl1ere is'a space between their ends and the .rim oi the wheel. Each o' thc-se sections is provided 'ad jacent to its side edges with d dove-` tailed shaped projection 5, andadjacent to the sides of the tread of the sections with a painof projections 6, 6,

to prevent sliding. The endsoi the sections are preferably beveled, as sliown in Figs. 1, 3 .and 4. At one endthey are beveled outwardly, asshown at 7 in Fig. 60 3, and at' the other end are beveled inwardly or under, cut, as-shown at 8 in Fig. 3.

, 1 In Fig. 4 the bevel 7 is recessed, as at 10, which recess tapers, at each end thereof, as shown at 11. This i recess is to receive the clamps 14, as shown at 14 in 65 Fig. 1, tolprevent forward movement of the protecting section. The sections are placed on the tir'e so that they form a solid tread with the bevel on one end of o'ne section adjacent to the undercut portion-'of the next section, 70 as is shown in the broken away portion of Fig. l. This will cause the dovetailed projections 5 to come into register with each other and form a dovetailedprojecy tion extending all the way around each side of the armor. `12 are-segmental bands provided with a-dovetai1ed groove 13 formed in one side. The bands 12 are formed in segments of the circle, and are of such a size that the dovetailed grooves -13 may be connected tothe dovetailed projections 5, so that the bands'l2 will extend 80 around the tire on each side thereof. This will effect thel locking together of all the sections 4 ofthearmor. i The groove 13 preferably, and askshowvn; does not eri-4` tend the full length of the'bands, but on one end stops' just short of the end, whereby the sections will be prevented *from creeping in relation to the bands. In order to securely hold the bands 12 in place, and to prevent displacement thereof, 'I provide clamps 14, which consist of a pair of bars 15, having their outer ends so shaped as to come up 'and abut againstthe pro- 90 jection 6 of the sections, and their other ends cometogether inside the rim 3, the inner ends being provided with ears '16 through. which a bolt 17 may be passed. In the form'. shown, I have used but four of these clamps. It is evident however that the number may be increasedor diminished Without departing from my invention. As shown in Figxl, theclamps14 are so arranged as to cover the adjacent'ends ofthe bands l2. By the use of the form of clamps shown, the-armor is securely held on the tire without affecting-the resiliency thereof, as vthe clamps are notscured to the rim, but are-free to move away from the rim under the in- *fluen'ce of pressure o n the tire."

While I have describedwhat ferred form of my invention, I desire to have it understood` that many changes maybe made in the form, construction and airangemlentof parte, without depasting from the spirit of my invention, so far as the .changes are embraced within .the sqopof the append ed claims. i i

1 believe tobe the pre- What I claim as new and desire to secue by Letters Patent is 1. 'An armor for tires, consisting of a series of independent protecting sections, projections formed on `the sides'of said sections, 4segmental bands extending completely around the sides of the tire and each provided with a groove in its side 'foi-'engaging the projections to hold the protecting sections in position, each of said segments being of a length to engage the projections on a plurality of the sections.

2. An armor for tires, consisting of a plurality ef independent protect-ing sections, each section, being formed with a beveled endpand an undercut end whereby the sections may overlap :ind form a smooth tread surface, projections formed on the outer sides of said sections, segmental bands extending completely around the sidesof the tire,V and each provided with a groove in its side for engaging the projections to hold the protecting sections 'in position, f

each of said segments being of n. length to engage the projections on u plurality of said sections.'

An armor for tires. consisting of a series of independent protecting sections` projections formed on the sides of said sections, segmental bands cach provided with a groove n one side thereof adapted to engage said projections, Suid segments extending around the sides of the tire to hold the protecting sections in position. each of said bands being of a length to engage the projections on n plurality of the sections, and clamps `adapted to engage the segments and the protecting 'sections to secure the armor to u wheel.

In testimonv whereofv I affix my signature, in presence of two-witnesses CHARLES P. MAYS.
